Bring in the sunshine! Yellow has made a massive comeback as the primary color for interior design, mainly because it’s associated with warmth and optimism. Whether you switch up your furniture or add a statement decoration, using primary colors against a muted palette will create a fresh and contemporary look. Yellow decorations, such as pillows and lamps, will help brighten up a room that otherwise doesn’t take in much natural light. Yellow walls, on the other hand, can be a little bit overpowering. If you’re unsure, try it out with peel-and-stick wallpaper!
